摘要:
Biologically active drugs, e.g. catecholamine hormones, are coupled to carrier molecules, e.g. monodisperse peptides to produce conjugate molecules. The conjugate molecules retain biological activity, but the pharmacokinetic, pharmacodynamic and/or potency properties of the drug is modified. The drug is coupled to the carrier via a spacer moiety which not only serves to covalently link the drug to the carrier, but also insulates the biologically active portion of the drug, i.e., the pharmacophore, from degradation during the coupling process. The carrier preferably consists of a monodisperse peptide in which the sequence of amino acid residues is carefully preselected and controlled.

摘要:
Phaffia rhodozyma strains are described which produce greater than 3,000 ppm astaxanthin based on dry yeast solids when cultivated in a volume of nutrient medium of at least about 1,500 liters and containing in excess of 4 percent, preferably in excess of 6 percent, dry yeast solids. These and other strains are cultivated by an improved fermentation method comprising extending the maturation phase of the fermentation by one or more various techniques including exposing the yeast cells to a low-intensity light, slow feeding the cells with a rapidly metabolized energy source, e.g. glucose, and replacing the rapidly metabolized energy source with a slowly metabolized energy source, e.g. gylcerol. The cells of these strains are incorporated into animal feeds, particularly feeds for salmonid fishes, to impart or enhance the red pigmentation of these animals and products made from these animals.

摘要:
A pigment library and a method for preparing it are provided, which includes identifying a plurality of thermoplastic polymers and then selecting pigments useful in the plurality of thermoplastic polymers. The pigments are heat stable at the melt temperature of each of the plurality of thermoplastic polymers and are not chemically interactive or reactive with each of the polymers of the plurality of thermoplastic polymer. Further, each of the pigments in combination with each of the polymers of the plurality of thermoplastic polymers possesses the property of being lightfast, injection moldable, and fiber spinnable and also not crocking. A colorant database is then prepared using the pigment library. The colorant database is used with color matching software that predict formulations using the colorant database. The result is the development of formulations that minimize or eliminate metameric color effect under various lighting conditions across multiple polymers and end product types.
